Water, air & soil pollution
Run by School of Natural Sciences
20 Credits or 10 ECTS Credits
Organiser: Dr Hilary Ford
Overall aims and purpose
As a professional environmental consultant, environmental engineer, policy advisor or town and country planner you will be expected to understand the underlying principles associated with air, soil and water quality. A major part of this requires an understanding of how manmade pollutants affect the biosphere and the impact on humans and also their impact on plants. This central course in environmental science/management is therefore designed for students with the above training in mind. It deals with major global environmental topics such as heavy metals, microplastics, pesticides, human pathogens, biodiversity loss from rivers, acid rain, salinity, water scarcity etc. In addition it covers aspects of environmental UV exposure and elevated ozone, radioactivity and eutrophication. This material is provided with reference to underpinning scientific information (e.g. on soil, water and air) and complementary material on current UK policy. It also looks at the state of the environment at a national and global scale. This second year unit further develops the information provided in the first year introductory module of Ecosystem Function and Services and provides the groundwork for later modules dealing with more specific environmental soil issues (e.g. Tenerife Field Course). The module comprises 23 lectures and the equivalent of 4 practical sessions and runs in the first semester. The practicals include 1 field trip (to Henfaes to look at soil, water and plants and 3 lab classes on aspects of air, water and soil pollution. The practicals will also enable students to use the basic statistical skills they learnt in Year 1 in real life situations. In summary, the purpose of the module is as follows: 1. To provide students with knowledge of the current environmental pollution problems associated with the terrestrial biosphere in a UK and global context. 2. To provide students with a theoretical knowledge of the chemical and biological nature of pollutants. 3. To provide students with a practical knowledge of how to determine pollutant concentrations, the effects of pollutants on vegetation, and how to do environmental risk assessment.

|Exam for Water, Air and Soil Pollution||60|
Teaching and Learning Strategy
23*1 hour lectures taught by a range of staff within SNS
1*4 hour field practical class. The practical class forms the foundation for the first 2 lab classes and is compulsory. The field practical is based at Henfaes. the field class demonstrates soil quality assessment techniques in the field (focused on a saltmarsh and agricultural grassland).
3*3 hour laboratory practicals. The first two sessions are linked to Practical Report 1 (Soil quality) and the third practical is related to Practical Report 2 (Soil pollution and remediation).
Private and guided self-study. This will be for background reading and preparing practical reports etc.
- Literacy - Proficiency in reading and writing through a variety of media
- Numeracy - Proficiency in using numbers at appropriate levels of accuracy
- Computer Literacy - Proficiency in using a varied range of computer software
- Self-Management - Able to work unsupervised in an efficient, punctual and structured manner. To examine the outcomes of tasks and events, and judge levels of quality and importance
- Information retrieval - Able to access different and multiple sources of information
- Inter-personal - Able to question, actively listen, examine given answers and interact sensitevely with others
- Critical analysis & Problem Solving - Able to deconstruct and analyse problems or complex situations. To find solutions to problems through analyses and exploration of all possibilities using appropriate methods, rescources and creativity.

Resource implications for students
They need to have their own lab coat for the laboratory practicals. They need outdoor wear (boots, waterproofs etc) for the field class.
